Description

Technical Field

[0001] This invention relates to the field of renewable resource recycling equipment technology, and more specifically, to a renewable resource recycling crusher. Background Technology

[0002] The recycling crusher is specifically designed for the resource recovery of solid waste such as scrap metal, construction waste, plastics, and tires. It combines powerful hammering and shearing crushing with efficient screening to rapidly refine materials and effectively separate impurities and metals, facilitating subsequent sorting and recycling. The machine features a robust structure, prioritizes energy saving and noise reduction, and is equipped with an intelligent control system, significantly improving recycling efficiency and reducing operating costs. It is a key piece of equipment for realizing a circular economy and promoting green recycling.

[0003] Patent application number CN202511999754.7 discloses a metal waste recycling and processing device and its usage method, including a machine base, an installation box installed on the top of the machine base, a feeding hopper installed on the top of the installation box, a crusher installed inside the installation box, two rollers rotatably installed inside the crusher, a high torque motor installed on the right end of the rear roller, and a retaining block installed on the outer side of both the front and rear rollers; by providing a retaining block, when the hardness of the metal material is high, causing the roller torque and bearing friction to increase, the push block drives the retaining block to press against the roller along the slide, cooperating with the inner roller to roll and resist, providing support force compensation for the roller.

[0004] In existing equipment, magnetic separation and crushing are usually separated. The material after initial tearing needs to be transferred between the magnetic separation equipment and the crushing equipment via a conveyor belt. This results in a large footprint, long material flow path, and loose system layout. At the same time, the accumulation and unloading of magnetic material after magnetic separation and the driving of the crushing rollers each require independent power sources. This usually requires multiple motors and corresponding transmission mechanisms, which not only leads to complex structure and high manufacturing cost, but also results in high energy consumption due to long-term idling or frequent start-stop of multiple motors.

[0005] In view of this, we propose a recyclable resource recovery crusher. Summary of the Invention

[0006] The purpose of this invention is to provide a recyclable resource recovery crusher, which integrates a magnetic separator above the crushing chamber. After the material is separated by the magnetic separator, the non-magnetic material falls directly into the non-magnetic material crushing chamber, thus realizing the integration of magnetic separation and crushing, and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A recycling crusher for renewable resources includes a crushing device, which includes a crushing chamber and a pair of non-magnetic crushing rollers and a pair of magnetic crushing rollers disposed on the left and right sides of the crushing chamber. A magnetic separator is provided above the crushing chamber. The magnetic separator includes a magnetic separation chamber, a magnetic separation cylinder that is rotatably installed inside the magnetic separation chamber, and a flip plate at the bottom of the magnetic separation chamber. One end of the flip plate is provided with a linkage component that drives it to flip. The crushing chamber is also equipped with a connector, which includes a short bushing coaxially connected to one of the non-magnetic crushing roller shafts, a long bushing coaxially connected to one of the magnetic crushing roller shafts, a push plate driven by a cylinder, an insert rod driven by the push plate, and a transmission component sleeved at the end of the insert rod. The transmission component includes a transmission tube and several levers that are elastically embedded in the wall of the transmission tube. In the above configuration, when the push plate moves to the first position where it contacts the linkage component, the transmission tube is inserted into the short bushing, and the paddle extends radially and engages with the groove on the inner wall of the short bushing to transmit power to the magnetic crushing roller; then it continues to move from the first position, driving the linkage component to drive the flip plate to flip down to unload the material, while the insert rod continues to extend into the transmission tube to restrict the paddle from retracting, so that the transmission component and the short bushing remain engaged and self-locking.

[0008] In the technical solution of the present invention, the internal partition of the crushing chamber divides the crushing chamber into a non-magnetic material crushing chamber and a magnetic material crushing chamber. The non-magnetic material crushing roller is rotatably connected to the non-magnetic material crushing chamber, and the pair of magnetic material crushing rollers are rotatably connected to the magnetic material crushing chamber. The connector is located in the area between the non-magnetic material crushing chamber and the magnetic material crushing chamber.

[0009] In the technical solution of the present invention, the crushing device further includes roller end gears coaxially connected to the ends of the roller shafts of the non-magnetic crushing roller and the magnetic crushing roller, a first motor unit fixed to the outside of the crushing chamber, a protective box sleeved on the non-magnetic crushing roller, and a protective box fixedly connected to the outside of the walls of the non-magnetic crushing chamber and the magnetic crushing chamber by bolts; the output shaft of the first motor unit is connected to the roller shaft of one of the non-magnetic crushing rollers, and the roller shafts of both the non-magnetic crushing roller and the magnetic crushing roller are rotatably supported by a shaft seat.

[0010] In the above configuration, by dividing the crushing chamber into two cavities and configuring a first motor unit, the selective operation of the two-cavity crushing rollers can be achieved by one machine driving them through a connector, thus achieving the effects of energy saving, consumption reduction and compact structure.

[0011] In the technical solution of the present invention, the magnetic separation chamber is arranged above the non-magnetic material crushing chamber and the magnetic material crushing chamber, and the flipping direction of the flap is towards the magnetic material crushing chamber.

[0012] In the technical solution of the present invention, the linkage component includes a shaft tooth, a toothed plate and a connecting beam. The shaft tooth is coaxially fixed with one end of the flip plate near the magnetic crushing roller. The toothed plate meshes with the shaft tooth and is fixed on the connecting beam. The longitudinal section of the connecting beam is U-shaped. The connector drives the toothed plate to translate by pushing the connecting beam, thereby meshing with the shaft tooth to drive the flip plate to flip.

[0013] In the technical solution of the present invention, the inner wall of the magnetic separation chamber is further welded with a feeding plate, a limiting plate, an arc-shaped baffle and a guide plate; the feeding plate is inclined upward from the left feed inlet of the magnetic separation chamber, the limiting plate is located below the magnetic separation cylinder, guiding the non-magnetic material that has not been adsorbed to the non-magnetic material crushing chamber, the guide plate extends inclined downward from the right side of the magnetic separation cylinder, guiding the adsorbed magnetic material to the top surface of the flip plate, and the arc-shaped baffle is located on the flipping path of the flip plate, adapting to the rotation trajectory of the flip plate, preventing the magnetic material from scattering outward when the flip plate flips to unload.

[0014] In the technical solution of the present invention, the magnetic separator further includes a second motor unit and a cover plate fixedly connected to the outer wall of the magnetic separator chamber by bolts. The output shaft of the second motor unit drives the magnetic separator drum to rotate, and a sliding groove for sliding of the linkage component is also provided on the bottom surface of the cover plate.

[0015] In the above setup, the coordinated layout of the magnetic separator, flap, and linkage components enables automatic magnetic separation and directional unloading of materials before crushing. The arc-shaped baffle ensures accurate unloading path, improving sorting efficiency and reliability.

[0016] In the technical solution of the present invention, the connector further includes a spline shaft rotating at the bottom end of the push plate and a first spring sleeved on the outside of the plug rod. The spline shaft slides axially inside the long shaft sleeve. Two limiting rings are integrally formed on the shaft wall of the spline shaft. The cylinder is fixedly connected to the outside of the cavity wall of the magnetic material crushing chamber by bolts. The telescopic end of the cylinder is fixedly connected to the push plate by bolts.

[0017] In the technical solution of the present invention, the transmission component further includes two round rods welded to the outer wall of the lever and a second spring sleeved on the outside of the round rods. The outer wall of the transmission tube is provided with a plurality of receiving grooves, and the inner wall of the transmission tube is provided with a through hole communicating with the receiving grooves. The two ends of the first spring are respectively welded and fixed to the spline shaft and the end of the transmission tube.

[0018] In the technical solution of the present invention, the axial end faces of the lever are outwardly inclined arc-shaped surfaces. The second spring applies a radially outward elastic force to the lever, so that when the transmission tube is inserted into the short bushing, the lever can be squeezed back and then ejected into the groove. When the push plate continues to move from the first position, the spline shaft pushes the insert rod into the transmission tube and compresses the first spring. The end face of the insert rod abuts against the inner end face of the lever to lock the radially extended state of the lever and restrict its retraction.

[0019] In the above configuration, the two-stage movement of the push plate, combined with the elastic engagement of the paddle block and the mechanical locking of the insert rod, prevents the transmission from disengaging while transmitting power to drive the magnetic material crushing roller, thus ensuring a stable and reliable crushing process.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. This recyclable material recovery crusher integrates a magnetic separator above the crushing chamber. After the material is separated by the magnetic separator, the non-magnetic material falls directly into the non-magnetic material crushing chamber, while the magnetic material accumulates on the flap plate. Once a certain amount has accumulated, the flap plate flips over and discharges the material into the magnetic material crushing chamber, thus achieving the integration of magnetic separation and crushing and reducing the material transfer path.

[0021] 2. This recyclable material recovery crusher, by setting up a connector, can simultaneously drive non-magnetic material crushing rollers and magnetic material crushing rollers with a single motor set. Only when magnetic materials need to be crushed, the transmission components are engaged by a cylinder, achieving selective power transmission and saving energy and reducing consumption.

[0022] 3. The two-stage moving stroke design of the push plate in this recycling crusher allows for seamless connection between power transmission and unloading sequence. Power is engaged first, followed by unloading, ensuring that the magnetic crushing roller starts rotating before the magnetic material falls in, thus avoiding starting under load. Simultaneously, during the unloading process, the insert rod is inserted into the locking block, using mechanical locking rather than relying solely on spring force to maintain engagement, effectively preventing transmission disengagement caused by the impact of high-hardness magnetic materials.

Detailed Implementation

[0024] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Please see Figures 1-2 As shown, this embodiment provides a technical solution: A recyclable resource recovery crusher includes a crushing device 100, which includes a crushing chamber 110 and a pair of non-magnetic crushing rollers 120 and a pair of magnetic crushing rollers 130 disposed on the left and right sides of the crushing chamber 110.

[0026] Specifically, the crushing device 100 also includes a roller end gear 140 coaxially connected to the ends of the roller shafts of the non-magnetic crushing roller 120 and the magnetic crushing roller 130, a first motor unit 150 fixed to the outside of the crushing chamber 110, a protective box 170 sleeved on the non-magnetic crushing roller 120 and fixed to the outside of the walls of the non-magnetic crushing chamber 111 and the magnetic crushing chamber 112 by bolts, which covers the roller end gear 140 inside, and plays a role in safety protection and dust prevention.

[0027] Furthermore, the internal partition of the crushing chamber 110 divides the crushing chamber 110 into a non-magnetic material crushing chamber 111 and a magnetic material crushing chamber 112. The non-magnetic material crushing roller 120 is rotatably connected to the non-magnetic material crushing chamber 111, and a pair of magnetic material crushing rollers 130 are rotatably connected to the magnetic material crushing chamber 112. The connector 300 is located in the area between the non-magnetic material crushing chamber 111 and the magnetic material crushing chamber 112.

[0028] Furthermore, the output shaft of the first motor unit 150 is connected to the roller shaft of one of the non-magnetic crushing rollers 120, directly driving the non-magnetic crushing roller 120 to rotate. Then, through the meshing of the roller end gear 140, it drives the other non-magnetic crushing roller 120 to rotate in the opposite direction. The roller shafts of both the non-magnetic crushing roller 120 and the magnetic crushing roller 130 are rotatably supported by the bearing seat 160. After the connector 300 transmits the power, the output shaft of the first motor unit 150 synchronously drives a pair of magnetic crushing rollers 130 to rotate.

[0029] In the above configuration, by dividing the crushing chamber 110 into two chambers and configuring the first motor unit 150, the selective operation of the two-chamber crushing rollers can be achieved by one machine driving them through the connector 300, thus achieving the effects of energy saving, consumption reduction and compact structure.

[0030] Please see Figures 3-7 As shown, in this embodiment, a magnetic separator 200 is provided above the crushing chamber 110. The magnetic separator 200 includes a magnetic separation chamber 210, a second motor unit 220, a magnetic separation cylinder 230 rotatably disposed in the magnetic separation chamber 210, a flap 240 disposed at the bottom of the magnetic separation chamber 210, and a cover plate 280 fixedly connected to the outer wall of the magnetic separation chamber 210 by bolts. One end of the flap 240 is provided with a linkage component that drives it to flip.

[0031] Specifically, the linkage includes a shaft tooth 250, a toothed plate 260, and a connecting beam 270. The shaft tooth 250 is coaxially fixed with one end of the flap 240 near the magnetic crushing roller 130. The toothed plate 260 meshes with the shaft tooth 250 and is fixed on the connecting beam 270. The longitudinal section of the connecting beam 270 is U-shaped.

[0032] Furthermore, the magnetic separation chamber 210 is positioned above the non-magnetic material crushing chamber 111 and the magnetic material crushing chamber 112, and the flipping direction of the flap 240 is towards the magnetic material crushing chamber 112.

[0033] Furthermore, the inner wall of the magnetic separation chamber 210 is also welded with a feeding plate 211, a limiting plate 212, an arc-shaped baffle 213, and a guide plate 214. The feeding plate 211 is inclined upward from the left feed inlet of the magnetic separation chamber 210. The limiting plate 212 is located below the magnetic separation cylinder 230 to guide the non-magnetic material that has not been adsorbed to the non-magnetic material crushing chamber 111. The guide plate 214 extends inclined downward from the right side of the magnetic separation cylinder 230 to guide the magnetic material that has been adsorbed to the top surface of the flip plate 240. The arc-shaped baffle 213 is located on the flip path of the flip plate 240 and is adapted to the rotation trajectory of the flip plate 240 to prevent the magnetic material from falling outward when the flip plate 240 flips to unload.

[0034] Furthermore, the output shaft of the second motor unit 220 drives the magnetic separator 230 to rotate, and a sliding groove 281 for sliding of the linkage component is also provided on the bottom surface of the cover plate 280.

[0035] Furthermore, the external vibrating conveyor belt feeds the uniformly torn material into the magnetic separator 210. The material reaches the surface of the magnetic separator 230 along the feed plate 211. The magnetic separator 230 is driven to rotate by the second motor unit 220. The magnetic area on its surface adsorbs the magnetic material in the material. The non-magnetic material falls directly into the non-magnetic material crushing chamber 111 under the guidance of the limiting plate 212 and is crushed by the non-magnetic material crushing roller 120. The magnetic material rotates with the magnetic separator 230 to the guide plate 214. At this time, the magnetism in this area of ​​the magnetic separator 230 disappears, and the magnetic material falls into the top surface of the flip plate 240 and accumulates through the guide plate 214.

[0036] Furthermore, the tilting plate 240 is located at the bottom of the magnetic separation chamber 210, above the inlet of the magnetic material crushing chamber 112. When not tilted, the tilting plate 240 is in a horizontal supporting state, used to receive and accumulate magnetic materials. A pressure sensor can be integrated into the supporting surface of the tilting plate 240. When the accumulated magnetic material reaches a preset weight, the pressure sensor sends a signal to trigger the subsequent connector 300. After the tilting plate 240 tilts, it unloads the magnetic material into the magnetic material crushing chamber 112. An arc-shaped baffle 213 is located on the tilting path of the tilting plate 240, its arc contour adapting to the rotation trajectory of the tilting plate 240. When the tilting plate 240 tilts to unload, it prevents the magnetic material from scattering outwards, ensuring that the material accurately enters the magnetic material crushing chamber 112.

[0037] Furthermore, the connector 300 drives the toothed plate 260 to translate by pushing the connecting beam 270, which in turn engages the shaft tooth 250 to drive the flip plate 240 to flip, and then crushes the unloaded magnetic material through the magnetic crushing roller 130 that has started to rotate.

[0038] In the above setup, the coordinated arrangement of the magnetic separator 230, the flap 240 and the linkage components enables automatic magnetic separation and directional unloading of materials before crushing. The arc-shaped baffle 213 ensures accurate unloading path and improves sorting efficiency and reliability.

[0039] Please see Figures 8-13 As shown, in this embodiment, the crushing chamber 110 is also provided with a connector 300. The connector 300 includes a short bushing 310 coaxially connected to the shaft of one of the non-magnetic crushing rollers 120, a long bushing 320 coaxially connected to the shaft of one of the magnetic crushing rollers 130, a push plate 340 driven by a cylinder 330, a spline shaft 350 rotating at the bottom of the push plate 340, an insertion rod 360 driven by the push plate 340, a first spring 370 sleeved on the outside of the insertion rod 360, and a transmission component 380 sleeved at the end of the insertion rod 360. The axis of the long bushing 320 and the short bushing 310 are collinear.

[0040] Furthermore, the spline shaft 350 slides axially inside the long shaft sleeve 320. Two limiting rings 351 are integrally formed on the shaft wall of the spline shaft 350 to limit the axial relative position between the spline shaft 350 and the push plate 340. The cylinder 330 is fixedly connected to the outside of the cavity wall of the magnetic material crushing chamber 112 by bolts. The telescopic end of the cylinder 330 is fixedly connected to the push plate 340 by bolts.

[0041] Furthermore, the transmission component 380 includes a transmission tube 381, several levers 382 elastically embedded in the wall of the transmission tube 381, two round rods 383 welded to the outer wall of the levers 382, ​​and a second spring 384 sleeved on the outside of the round rods 383. The insertion rod 360 can only move along the axial direction of the transmission tube 381 and rotate synchronously with the transmission tube 381.

[0042] Furthermore, a number of receiving grooves 3810 are provided on the outer wall of the transmission tube 381, and a through hole 3811 communicating with the receiving grooves 3810 is provided on the inner wall of the transmission tube 381. The two ends of the first spring 370 are welded and fixed to the spline shaft 350 and the end of the transmission tube 381, respectively.

[0043] Furthermore, the two axial end faces of the lever 382 are outwardly inclined arc-shaped surfaces. The second spring 384 applies a radially outward elastic force to the lever 382, ​​so that when the transmission tube 381 is inserted into the short bushing 310, the lever 382 can be squeezed back and then popped into the groove. When the push plate 340 continues to move from the first position, the spline shaft 350 pushes the insert rod 360 into the transmission tube 381 and compresses the first spring 370. The end face of the insert rod 360 abuts against the inner end face of the lever 382 to lock the radially extended state of the lever 382 and restrict its retraction.

[0044] Furthermore, when the push plate 340 moves to the first position where it contacts the linkage, the transmission tube 381 is inserted into the short bushing 310. Under the elastic force of the second spring 384, the lever 382 extends radially and is inserted into the groove on the inner wall of the short bushing 310 to transmit power to the magnetic crushing roller 130. Then, it continues to move from the first position, driving the linkage to drive the flip plate 240 to flip down and unload the material. At the same time, the insert rod 360 continues to extend into the transmission tube 381. The end face of the insert rod 360 abuts against the inner end face of the round rod 383 to lock the radial extension state of the lever 382, ​​restricting the retraction of the lever 382, ​​so that the transmission member 380 and the short bushing 310 remain engaged and self-locked.

[0045] In the above configuration, the push plate 340 moves in two stages, and the lever 382 is elastically engaged and mechanically locked with the insert rod 360. This ensures that the transmission is not disengaged while transmitting power to drive the magnetic crushing roller 130, thus ensuring a stable and reliable crushing process.

[0046] The recyclable resource recovery crusher of the present invention includes the following steps in use: In the initial state, the cylinder 330 is in the retracted state, the push plate 340 is in the initial position, the transmission component 380 and the short bushing 310 are separated, there is a gap between the push plate 340 and the connecting beam 270, the first motor group 150 starts, drives the non-magnetic material crushing roller 120 to rotate, and the magnetic material crushing roller 130 remains stationary. An external vibrating conveyor belt feeds the uniformly torn material into the magnetic separator 210. The material reaches the surface of the magnetic separator 230 along the feed plate 211. The magnetic separator 230 is driven to rotate by the second motor unit 220. The magnetic area on its surface adsorbs the magnetic material in the material. The non-magnetic material falls directly into the non-magnetic material crushing chamber 111 under the guidance of the limiting plate 212 and is crushed by the non-magnetic material crushing roller 120. The magnetic material rotates with the magnetic separator 230 to the guide plate 214. At this time, the magnetism of that area of ​​the magnetic separator 230 disappears, and the magnetic material falls into the top surface of the flip plate 240 and accumulates through the guide plate 214. When the magnetic material on the flap 240 accumulates to a preset weight, the cylinder 330 is activated, pushing the push plate 340 from the initial position to the first position. During this process, the push plate 340 drives the transmission component 380 to approach the short bushing 310. The transmission tube 381 is gradually inserted into the short bushing 310. When the arc-shaped end face of the lever 382 contacts the port of the short bushing 310, it is squeezed and radially retracted. After the transmission tube 381 is inserted into place, the lever 382 extends radially under the action of the second spring 384 and is inserted into the groove on the inner wall of the short bushing 310, realizing power engagement. At this time, the push plate 340 reaches the first position and just contacts the bottom crossbeam of the connecting beam 270, but has not yet pushed the connecting beam 270 to move. As cylinder 330 continues to extend, push plate 340 continues to move from the first position. Push plate 340 pushes connecting beam 270 to translate along slide groove 281. Connecting beam 270 drives toothed plate 260 to move. Toothed plate 260 meshes with shaft tooth 250 to rotate, thereby driving flap 240 to flip and unload the accumulated magnetic material into magnetic material crushing chamber 112. Arc baffle 213 prevents material from scattering during this process. At the same time, as push plate 340 continues to move, spline shaft 350 compresses first spring 370 and pushes insert rod 360 to continue extending into through hole 3811 of transmission tube 381. End face of insert rod 360 abuts against inner end face of round rod 383 to lock the radial extension state of lever 382, ​​restricting its retraction, so that transmission component 380 and short bushing 310 remain engaged and self-locked. At this time, the power of the first motor unit 150 has been transmitted to the magnetic crushing roller 130 through the connector 300. The magnetic crushing roller 130 starts to rotate and crushes the unloaded magnetic material. Since the power has been engaged before the flip plate 240 flips to unload the material, the magnetic crushing roller 130 is already in operation when the magnetic material falls in, avoiding starting under load. At the same time, the mechanical locking of the insert rod 360 to the toggle block 382 ensures that the transmission component 380 will not accidentally come off the short shaft sleeve 310 due to impact during the crushing of high hardness magnetic materials, thus ensuring the stability of power transmission. After unloading is completed, cylinder 330 retracts, driving push plate 340 from the second position through the first position back to the initial position. During the return process, push plate 340 first disengages from connecting beam 270, and flip plate 240 resets to the horizontal support state under the action of gravity; insert rod 360 exits from transmission tube 381 under the elastic force of first spring 370, and toggle block 382 is unlocked; transmission component 380 disengages from short bushing 310, power transmission of magnetic crushing roller 130 is disconnected, and it returns to the state where only non-magnetic crushing roller 120 operates, waiting for the next accumulation of magnetic material to repeat the above working cycle.

[0047] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations. The scope of the invention is intended to be defined by the specification and its equivalents.
